Specification of Letters Patent.

Patented Aug. 14, 1.906.

Application led August 11,1905. Serial No. 273,815.

Be it known that I, HENRY STOLTENBERG, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Cyluider-Cooling,` Devices for Gasolene-Engines, of which the following is a full7 clear7 and exact description, such as will enable others skilled in the art to which the saine appcrtains to malte and use the saine.

My invention relates more particularly to gas-eiiu'incs and its object is to provide a rcmovabxle device which can be applied with equal facility to the fly-wheels ol either new or old gas-engines and will as said wheel rcvolves direct a current of air to and past the cylinder to assist in diffusing` the heat generated therein and carry away the surface heat thereof. This I accomplish by the means hereinafter fully described and as particularly pointed out in the claims.

ln the drawings, Figure l is a side view of the fly-wheel of a gas-engine, showing my iniprovcnieiits applied thereto. Fig. 2 is a section of a portion thereof drawn to a larger scale. Fig. 3 is a transverse section of the same, taken on dotted line 3 3, Fig. 2. Fig. 4 is a detail plan view of a portion of the rim of thc ily-wheel, showing' the oblique arrangement of the vanos or fans.

In the drawings, A represents the cylinder o'f a gas-engine, B the drive-shaft thereof, and t) the fly-wheel on said drive-shaft. My invention consists of a circular band or rini l), of sheet metal, which is fitted upon and is clamped to the peripheryof said fly-wheel. This band is preferably of a slightly greater' width than the periphery of said fly-Wheel and has its longitudinal edges (L a. provided with interiorly-projecting: beads, which are made by bending said edges around the wire fillers b I). When the band D is properly fitted upon the rini of the wheel, these beads lap over and inclose the outer edges of the fly-wheel and prevent the lateral displacement ofthe band. The lateral displacement of the band might be prevented in some other manner, however, although I refer the use of the beads` The band is prefldrably of such length that the ends c c thereof overlap. The outermost end c has a transverse angle-strip d of met-al secured thereto by rivets 0r otherprojecting: portion opposes the outwardly-l projectingportion of stripe. The outwardlyprojecting portions of these transverse anglestrips are connected by boltsff, which are passed through suitable openings and tightene'd by nuts g g, so as to draw said ends together and securely clamp the band on the. rim of the fly-wheel. The band D has secured thereto and proj eating outwardly therefrom oblique to the line of motion thereof a series of varies or fans E E, which are preferably located equal distances apart and are of corresponding,r shape and dimensions. These vanos or fans may be of any suitable design, so that when the fly-wheel revolves they will propel a continuous current of cool air against and past the cylinder, thus carrying' away a considerable amount of heatcoming to the surface of the cylinder andl diffusing the heat of the outer surface of the cylinder and lowering the temperature thereof.

What I claim as new is-- l. In an engine theI combination with a fly- Wheel of a circular flat band secured on and extending around the peri )hery of said wheel and having downwardly-lianged edges; a series of diaironally-disposed vanes secured to the outer surface of said band; angle-shaped clamping-strips secured transversely to said band near each end thereof; and means for clamping the ends of said band together.

2. In an engine the combination with a flywheel; of a circular flat band secured on and extending around the periphery of said wheel and having downwardly-flanged edges and overlapping ends; a series of diagonally-disposed vanes secured to the outer surface of said band; angle-shaped clanipine-stri )s sci cured transversely to said band near eac i end thereof; and means for clamping the ends of said band together.

3. In an engine the combination with a flvwheel ;iof. a circular flat band surrounding the periphery of said wheel and having its longitudinal edges beaded; a series of ont-4 wardly-projecting diagonally-arranged vanes proJecting from the outer surface of said and angle-shaped clainpuig-strips secured IOC transversely to saidband near the ends tlierel versely to said hand near the ends thereof;

of; and bolts connecting the outwardly-projectinfr portions of said clamping-strips.
